Enabling or disabling the write filter

This step shows how to enable or disable a write filter under TwinCAT/BSD. Note that the changes to the write filter only take effect after a restart.

Proceed as follows:

1. Enter the command doas service bwf enable in the console to enable the write filter.

2. Confirm the command with the administrator password.

Administrator@CX-3D6912:~ $ doas service bwf enable
Password:
bwf_enable: NO -> YES
writefilter enabled, please reboot to make your changes take effect.

3. Restart the Industrial PC with shutdown -r now to apply the settings.

The write filter is active after the restart. The write filter is deactivated again with the command doas service bwf disable.
